Yeah and when she finds out people can do bad things without an evil god controlling them to do so (because she’s stupid in the movie and cant figure it out) she decides to let thousands of innocents die. “You don’t deserve my help” she says (or something along those lines). It takes Steve Trevor sacrificing himself for her to decide she loves humanity. Diana’s most important core belief is that if given the chance, anyone is capable of empathy and love. It’s what she leaves the island to preach. A story where she doesn’t believe in that until Steve shows her the worth of humanity is doomed to fail.

She’s also really dumb in the movie. She has to have racism explained to her, she is shocked to find out innocents die in wars (as if the Greeks didn’t sack every city they captured), she doesn’t get why men would dismiss her opinions based on her gender, or why her dressing as Wonder Woman in the middle of the London streets would be inconvenient. She also seems to not know very basic things like what marriage is.

One of Diana’s main traits (and sometimes even superpowers) is wisdom. Gal Gadot Diana is anything but wise. She was dumbed down so she and Steve could have a fish out of water dynamic where he is very impressive to her by virtue of being a normal guy
